  1. how many lumens does a 400w hps produce?
  2. Depends on the bulb, but typical would be around 45,000.
  3. HOLY JUMPIN FUCKIN JESUS are you serious? wont you go blind looking at that?
  4. haha I don't think you'll go blind, but staring directly at it from a close distance is not recommended. haha.
  5. and i thought my 2600 lumen fluro was bright as shit. damn. now i understand what all the fuss is about with the hps
